  • Deep Learning for Robust Normal Estimation in Unstructured Point Clouds 

    Boulch, Alexandre; Marlet, Renaud (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Normal estimation in point clouds is a crucial first step for numerous algorithms, from surface reconstruction and scene understanding to rendering. A recurrent issue when estimating normals is to make appropriate decisions ...
  • Mesh Statistics for Robust Curvature Estimation 

    Váša, Libor; Vaněček, Petr; Prantl, Martin; Skorkovská, Věra; Martínek, Petr; Kolingerová, Ivana (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    While it is usually not difficult to compute principal curvatures of a smooth surface of sufficient differentiability, it is a rather difficult task when only a polygonal approximation of the surface is available, because ...
  • Disk Density Tuning of a Maximal Random Packing 

    Ebeida, Mohamed S.; Rushdi, Ahmad A.; Awad, Muhammad A.; Mahmoud, Ahmed H.; Yan, Dong-Ming; English, Shawn A.; Owens, John D.; Bajaj, Chandrajit L.; Mitchell, Scott A. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We introduce an algorithmic framework for tuning the spatial density of disks in a maximal random packing, without changing the sizing function or radii of disks. Starting from any maximal random packing such as a Maximal ...
  • Exploration of Empty Space among Spherical Obstacles via Additively Weighted Voronoi Diagram 

    Manak, Martin (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Properties of granular materials or molecular structures are often studied on a simple geometric model - a set of 3D balls. If the balls simultaneously change in size by a constant speed, topological properties of the empty ...
  • Symmetry and Orbit Detection via Lie-Algebra Voting 

    Shi, Zeyun; Alliez, Pierre; Desbrun, Mathieu; Bao, Hujun; Huang, Jin (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    In this paper, we formulate an automatic approach to the detection of partial, local, and global symmetries and orbits in arbitrary 3D datasets. We improve upon existing voting-based symmetry detection techniques by ...
  • Planar Minimization Diagrams via Subdivision with Applications to Anisotropic Voronoi Diagrams 

    Bennett, Huck; Papadopoulou, Evanthia; Yap, Chee (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Let X = {f1, . . ., fn} be a set of scalar functions of the form fi : R2 →R which satisfy some natural properties. We describe a subdivision algorithm for computing a clustered e-isotopic approximation of the minimization ...
  • Learning 3D Scene Synthesis from Annotated RGB-D Images 

    Kermani, Zeinab Sadeghipour; Liao, Zicheng; Tan, Ping; Zhang, Hao (Richard) (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present a data-driven method for synthesizing 3D indoor scenes by inserting objects progressively into an initial, possibly, empty scene. Instead of relying on few hundreds of hand-crafted 3D scenes, we take advantage ...
  • Identifying Style of 3D Shapes using Deep Metric Learning 

    Lim, Isaak; Gehre, Anne; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present a method that expands on previous work in learning human perceived style similarity across objects with different structures and functionalities. Unlike previous approaches that tackle this problem with the help ...
  • Construction of Topologically Correct and Manifold Isosurfaces 

    Grosso, Roberto (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present a simple method to describe the geometry and topologically classify the intersection of level sets of trilinear interpolants with a reference unit cell. The solutions of three quadratic equations are used to ...
  • Curve Reconstruction with Many Fewer Samples 

    Ohrhallinger, Stefan; Mitchell, Scott A.; Wimmer, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We consider the problem of sampling points from a collection of smooth curves in the plane, such that the CRUST family of proximity-based reconstruction algorithms can rebuild the curves. Reconstruction requires a dense ...
  • Crawl through Neighbors: A Simple Curve Reconstruction Algorithm 

    Parakkat, Amal Dev; Muthuganapathy, Ramanathan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Given a planar point set sampled from an object boundary, the process of approximating the original shape is called curve reconstruction. In this paper, a novel non-parametric curve reconstruction algorithm based on Delaunay ...
  • Data-Driven Bending Elasticity Design by Shell Thickness 

    Zhang, Xiaoting; Le, Xinyi; Wu, Zihao; Whiting, Emily; Wang, Charlie C. L. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present a method to design the deformation behavior of 3D printed models by an interactive tool, where the variation of bending elasticity at different regions of a model is realized by a change in shell thickness. Given ...
  • Interactive Modeling of Mechanical Objects 

    Ureta, Francisca Gil; Tymms, Chelsea; Zorin, Denis (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Objects with various types of mechanical joints are among the most commonly built. Joints implement a vocabulary of simple constrained motions (kinematic pairs) that can be used to build more complex behaviors. Defining ...
  • Non-Rigid Puzzles 

    Litany, Or; Rodolà, Emanuele; Bronstein, Alex M.; Bronstein, Michael M.; Cremers, Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Shape correspondence is a fundamental problem in computer graphics and vision, with applications in various problems including animation, texture mapping, robotic vision, medical imaging, archaeology and many more. In ...
  • Stable Region Correspondences Between Non-Isometric Shapes 

    Ganapathi-Subramanian, Vignesh; Thibert, Boris; Ovsjanikov, Maks; Guibas, Leonidas (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We consider the problem of finding meaningful correspondences between 3D models that are related but not necessarily very similar. When the shapes are quite different, a point-to-point map is not always appropriate, so our ...
  • Splines in the Space of Shells 

    Heeren, Behrend; Rumpf, Martin; Schröder, Peter; Wardetzky, Max; Wirth, Benedikt (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Cubic splines in Euclidean space minimize the mean squared acceleration among all curves interpolating a given set of data points. We extend this observation to the Riemannian manifold of discrete shells in which the ...
  • Stenciling: Designing Structurally-Sound Surfaces with Decorative Patterns 

    Schumacher, Christian; Thomaszewski, Bernhard; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present a novel method to design shells with artistic cutouts in a manner that produces a stable final result. The process of stenciling, removing material with a fixed shape, is a particularly appealing way to introduce ...
  • Mobility Fitting using 4D RANSAC 

    Li, Hao; Wan, Guowei; Li, Honghua; Sharf, Andrei; Xu, Kai; Chen, Baoquan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Capturing the dynamics of articulated models is becoming increasingly important. Dynamics, better than geometry, encode the functional information of articulated objects such as humans, robots and mechanics. Acquired dynamic ...

    Guo, Xuekun; Lin, Juncong; Xu, Kai; Chaudhuri, Siddhartha; Jin, Xiaogang (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Several applications in shape modeling and exploration require identification and extraction of a 3D shape part matching a 2D sketch. We present CustomCut, an on-demand part extraction algorithm. Given a sketched query, ...
  • Near-Isometric Level Set Tracking 

    Tao, Michael; Solomon, Justin; Butscher, Adrian (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Implicit representations of geometry have found applications in shape modeling, simulation, and other graphics pipelines. These representations, however, do not provide information about the paths of individual points as ...
